Title: Manufacture of high-purity metallic chromium
Inventor: TANAKA YOSHIO
IPC: C22B34/32
Filed: 1987-02-13
Abstract: PURPOSE:To manufacture a high-purity metallic chromium by subjecting Cr2O3 to carbon reduction, by forming a powder of chromium carbide-containing metallic chromium into a green compact by means of a binder material, and by subjecting the above compact to vacuum reduction in an atmospheric heat-treatment furnace and successively to gaseous reduction under reduced pressure in a reducing-gas atmosphere. CONSTITUTION:Cr2O3 is reduced by a carbonaceneous reducing agent, and crude metallic chromium containing chromium carbide such as Cr3C2, Cr7C2, Cr23C6, etc., is crushed into a pulverized powder of <=32mesh. Subsequently, an organic high polyer substance such as synthetic resin, gum arabic, dextrin, etc., as a binder material and a Cr2O3 powder as an oxidizing agent are mixed with the above pulverized powder, and the resulting mixture is compacted. The green compact is then charged into an atmospheric heat-treatment furnace, where, while heated up to >=1,200 deg.C and held, chromium carbide and Cr2O3 are allowed to react so as to decarburize C in chromium carbide in the form of CO, and further, gaseous reduction under reduced pressure is applied at the same temp. by means of a reducing gas such as H2, etc. In this way, high-purity metallic Cr minimal in respective contents of chromium carbide, Cr2O3, etc., can be manufactured.

Filed: 1978-03-17
Abstract: PURPOSE:To make it possible to effect the optical beam scanning operation having longitudinal extension by providing compensating means using an oval mirror to make uniform the optical beam scanning operation on a straight line on a scanning plane. CONSTITUTION:If an oval mirror 5 which is arranged to have its longer axis in parallel with a scanning plane 4 is used, the normal line n at each point on the reflecting plane 5a of the oval mirror 5 is inclined the steeper as it approaches the more from the center point 0 to the both ends A and A' so that the optical beam scanning speed on the straight plane in the scanning plane 4 and the distance from a rotary mirror 1 to a scanning point are made the same to make it possible to accomplish the optical beam scanning operations having a longitudial extension. Thus, it is possible to effect the sufficient compensation by selecting the distance between the rotary mirror 1 and the oval mirror 5 at its oval longer axis, the size (shape and size) of the oval mirror 5 and the position of the scanning plane 4.

Title: Ball catching implement (mitt)
Inventor: FUKAE TOYOJI
IPC: A63B71/14
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To prevent an injury of a thumb by fitting a part to house the thumb to a thickness of the thumb, and forming it in a bag shape to surround the whole thumb periphery. SOLUTION: A back skin 10 to cover the back of a hand is formed by using two skins 12 and 13, and a bag-shaped part 11 to house a thumb is formed. That is, the skins 12 and 13 are sewn together in an almost straight line shape in a part 14 touching the back of the thumb, and the bag-shaped part 11 is formed in a three-dimensional shape. Both side edges 15 and 16 of the bag- shaped part 11 are also sewn along an inside part and an outside part of the thumb. A part except for the part to house the thumb may be the same as a conventional mitt. By this constitution, the thumb in a condition of entering the bag-shaped part 11 opens in the size to the little finger side so as to easily catch a ball. Simultaneously when a ball enters the mitt, the thumb closes, and the ball is caught, and the bag-shaped part 11 fits to the whole thumb periphery.  Therefore, for example, even if a ball causing a foul tip strikes on a thumb side bank part, the mitt is not dislocated to a hand, and an injury of fingers can be prevented.

Title: Electronic still camera
Inventor: OGAWA MASAAKI
IPC: G11B5/024
Filed: 1990-02-09
Abstract: PURPOSE:To erase the arbitrary number of tracks with one operation by erasing the information of the inner peripheral or outer peripheral tracks from the arbitrary track. CONSTITUTION:When an erasing mode is commanded by a mode switch 13 and a select switch 14, a system controller 7 drives a liquid crystal display device 12 through a display control circuit 11 and turns an ERASE mark on/off. When an up switch 15 or a down switch 16 is operated, the display of a track number is increased or decreased and a magnetic head 4 is moved to the track of the number by a tracking motor control circuit 6 and a tracking motor 5. When the head 4 is positioned on the prescribed track, the erasing mark ERASE is turned on by a trigger switch 9 and when an exposure correcting switch 10 is not operated, a floppy disk 1 is rotated. Then, an erasing circuit 8 is operated. When one track is completely erased in such a way, a spindle motor is stopped. Thus, the desired number of tracks can be erased one by one.

CONSTITUTION:When a thunderbolt hits an aerial ground wire 1, a large lightning current I flows to cause a magnetic flux 4 and an induced voltage is generated in a coil 2 set in the vicinity thereof. As the voltage at the output terminal of an amplifier 10 rises higher than the reference voltage, the voltage at the output terminal of a comparator 13 moves to a low level and a flip flop circuit 14 is set, bringing the voltage at the Q output terminal to a high level. This turns ON a switching transistor 16 and a current flows from a power source 18 to light a display lamp 17.
